A growing body of evidence suggests that chronic low-grade inflammation and oxidative stress may lead to cancer development. These discoveries complement the usual focus prevention primarily concentrates on carcinomas, i.e., ectodermal or endodermal (embryonic) tissue-derived cancers, which are more exposed lifestyle/environment-related risk factors. Based these findings, preventive strategies ...

INTRODUCTION Psammocarcinoma of ovary is a rare serous neoplasm characterized by extensive formation of psammoma bodies, invasion of ovarian stroma, peritoneum or intraperitoneal viscera, and moderate cytological atypia. Extensive medlar search showed presence of only 28 cases of psammocarcinoma of ovary reported till date. CASE PRESENTATION We herein report a case of psammocarcinoma of ovary...

NK-2 class homeobox genes are candidate patterning and lineage regulators in diverse organisms. We report here the embryonic expression pattern of murine member, Nkx2-6. In keeping with its vertebrate relatives, Nkx2-6 was transcribed in ventrolateral embryonic structures. Expression was first detected at E8.0 in endodermal walls of the foregut pocket, tissue destined to become pharyngeal floor...
